All whole numbers are rational numbers.

Because both of those numbers are rational. The sum of any two rational numbers is rational.

Add them together and divide by 2 will give one of the rational numbers between two given rational numbers.

Integers are whole numbers. Rational numbers can be fractions / decimals. But it is NEVER a whole number E.G. of rational numbers : 3/4 or 1.5

Numbers are either irrational (like the square root of 2 or pi) or rational (can be stated as a fraction using whole numbers). Irrational numbers are never rational.

Rational number can be divided into more that the number 2. Irrational number are numbers that can only be divided evenly with the number 2.

All of the natural numbers are rational, but there are still more rational numbers that aren't natural ones. Example: 1, 2, 3, 4, and 5 are all natural numbers, and they're all rational. 11/2, 21/2, 31/2, 41/2, and 51/2 are also rational, but they're not natural numbers.

All rational numbers are fractional but all fractional numbers are not rational. For example, pi/2 is fractional but not rational.

It is a rational number.

There are an infinite number of rational numbers between any two rational numbers. And 2 and 7 are rational numbers. Here's an example. Take 2 and 7 and find the number halfway between them: (2 + 7)/2 = 9/2, which is rational. Then you can take 9/2 and 2 and find a rational number halfway: 2 + 9/2 = 13/2, then divide by 2 = 13/4. No matter how close the rational numbers become, you can add them together and divide by 2, and the new number will be rational, and be in between the other 2.

All integers are rational numbers. There are integers with an i behind them that are imaginary numbers. They are not real numbers but they are rational. The square root of 2 is irrational. It is real but irrational.

Yes it is. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
